Modern body cameras are often equipped with both 4G mobile networks and WiFi connectivity. The 4G module is mainly used for remote live transmission of video, audio, and GPS data, while WiFi is typically used for local data transfer, device configuration, or hotspot sharing. A common question is: can both networks be activated at the same time on a body camera?
Technical Principles
- 4G Network: Relies on a built-in communication module and SIM card, connecting directly to the operator’s base station for public network transmission.
- WiFi Network: Can operate in AP mode (hotspot) or STA mode (client) to connect the camera within a local area network or to a specified router.
While 4G and WiFi modules are physically independent and could theoretically run simultaneously, actual behavior depends on the device firmware and operating system’s network management policies.
Shelleyes Device Compatibility
Across the Shelleyes product line, most network-enabled models (such as S4, S8, and S29D) only support one network mode at a time. Users must choose between WiFi or 4G. The good news is that these models support quick manual switching between network modes, making it easy to adapt based on field requirements.
Currently, only S7P and S9 (Android OS) support true concurrent WiFi and 4G operation at the system level.
| Model | Dual Activation | Auto Switching | User Experience |
|---|---|---|---|
| S4 / S7/ S8 / S29D | ✘ (Single mode only) | ✘ (Manual switching required) | Ships with WiFi enabled by default, users must manually switch to 4G |
| S7P | ✔ | Partial (WiFi → 4G only) | Ensures transmission continuity, but does not auto-switch back to WiFi |
| S9 | ✔ | ✔ (Full flexibility) | Android-based, allows seamless switching and intelligent network management |
Practical Notes
- Default Mode: Since most Shelleyes models support only one network at a time, the factory default is WiFi Mode. Users can manually switch to 4G through the settings menu when needed.
- Hotspot Limitation: If the camera is running WiFi in AP mode (broadcasting a hotspot), 4G cannot be enabled simultaneously, as the channel is occupied.
Usability Insights
Although both S7P and S9 support concurrent WiFi and 4G, their user experience differs:
- S7P: When leaving a configured WiFi coverage area, the device automatically switches to 4G to ensure uninterrupted transmission. However, when returning to the WiFi area, it does not automatically reconnect to WiFi STA mode—manual switching is required. This design prioritizes continuity of remote transmission.
- S9 (Android OS): Powered by Android, the S9 offers far greater flexibility. Users can freely toggle between WiFi and 4G, with seamless switching and even OS-level intelligent policies for optimizing connectivity. This makes the S9 better suited for complex, multi-scenario environments.
Conclusion
Shelleyes body cameras are technically capable of supporting 4G and WiFi in parallel, but most models are limited to one active network at a time, shipping with WiFi enabled by default.
Currently, only S7P and S9 support true concurrent WiFi and 4G. The S7P emphasizes reliable remote transmission continuity, while the S9, with its Android-based system, delivers higher flexibility and user freedom in network management.
